State Regulation, Legislation and International Activities in the Water Sector

Summary

Issues of the state regulation and development of legislative basis in the sphere of water supply and sewerage services are covered. Currently, in the Russian Federation the following problems are not defined at the legislative level: the public and legal status of enterprises of water supply and sewerage services, methods of market regulation of water supply and water disposal services, rules of conduct for its participants, guarantees of safe, reliable and uninterrupted water supply and water disposal. To solve the issues raised it is necessary to have a united organizational center of activities aimed at legislative support of the water branch. To modernize the water sector it is proposed to reconstitute the scientific and technical council at the RF Ministry of Regional Development and organize the All-Russian data bank on the best available techniques as well.

Advanced methods of designing biological treatment facilities

Summary

The data of the analytical reviews and practical results of calculating and designing advanced wastewater treatment facilities are presented. The analysis of the methods of designing biological wastewater treatment facilities (construction rules and regulations SNiP, ATV) and the software for mathematical simulation of the facilities operation («EcoSim», GPS-X etc.) is made together with the hydrodynamic continuum mechanics software as applied to calculating the flow conditions at the treatment facilities. The mathematical model of biological wastewater treatment process is based on the analysis of the relationships of enzyme kinetics of the wastewater pollutant transformation and makes a connection between the parameters of the raw waste and effluent, dissolved oxygen concentration and activated sludge. The principles of designing and calculating the facilities for biological treatment of municipal and industrial wastewater including the use of nitri-denitrification and biological phosphorus removal processes have been developed. The practical experience of using the mentioned methods in front end and design works.
